You can sell anything to the young
> Nobody makes things that bad by accident, surely
They don't (it takes years of practice). However, if you make something truly bad, then you can still rely on the young, callow and stupid (meant in the nicest possible way, of course: let's call it trusting, open-minded and willing instead) to queue for hours to buy it. Provided of course you pitch it as being the latest thing that all their friends will have. Be the first on your street ... etc. etc.
For oldies however, it's a much harder sell. They (we?) tend to ask difficult questions, such as "yes, but what does it actually do?", or (case in point the up-coming Ubuntu LTS release) "but what will I be able to do with it, that I can't do with the old one?". There's also the not insignificant point that after some years, one tends to have all the stuff, clothes, gadgets and media that's useful, decorative or beneficial, already. After that it's more a case of just replacing worn out or broken stuff.
People with life-experience tend to be a lot more skeptical about novelty. Maybe it's a once bitten thing. Maybe it's a case of the money I have, I've had to work for (rather than being given an allowance, that just drops into my pocket), so I'm more cautious about what I spend it on. Whatever the reason, it's difficult for a wet-behind-the-ears sales person to sell to someone who can ask relevant questions, often based on experience, than it is to someone who just thinks "ooooh, shiney".
What that means is that all the marketing mulah will go on persuading the persuadable to spend their cash in one direction, or another. And not on the lost cause of enticing those who carefully read reviews, weigh up the pros and cons and then go off, in search of the best deal. What use is a full-page glossy ad, or 60 seconds of Superbowl publicity to those people?
